'lo'all whom it may concern:

Be it known that I, \VILLIAM A. residing at Niagara Falls, in the county of Niagara and State of New York, have m and useful Improvements in Cylinders for Printing-Presses, of which the following isa full, clear, and exact description, such as will enable others skilled in' the art to which it and use the same.

This .anism, v V SiCIIlCtlOII of plate or form cylinders adapted to be employed in rotary printing presses.

One of the objects of'the invention is-to eific'ient means for mounting printing devices upon a supporting shaft.

Another object is to provide improved means for carrying printin or numbering devices employed in printing mechanism of the above character.

Other objects will be in part obvious'and in Fart pointed out hereinafter. i

he'invention accordingly consists in the features of construction, combinations of following claims.

' erring now tothe accompanying drawelements and arrangement of parts which will be exemplified in the construction here inafter set forth, and the sco e of the application of which willbe in icated in the Ref ings, wherein is illustrated one of the va rious possible embodiments of my invention, Figure 1 is a view in. elevation of a supporting shaft, showing the manner of mounting the section thereon. Fig. 2 is a view in vertical section taken through the supporting shaft, showing the-means for mounting and actuating the printing devices carried there by. Fig. 3 1s aview in perspective of the outer end of a rock shaft'em 'aloyed for operating printing devices, showing the arm by means of which the same is actuated. Fig. 4 is a similar view of the means employed to enga e and actuate the printing devices carried y a; section mounted upon the shaft. is a view similar to Fig. 1, but on a smaller scale, showing a different type of cylinder for carrying printing devices. Fig. 6 is a view in end elevation showing the manner of mounting the printing devices upon the cylinder, some of the-parts being roken away so as better to disclose the con- PmNo-LE,

apperta-ins to m slge a shaft the block is Similar reference characters refer to simi lar parts througl outthe several views. eferring now to the drawings, 1 indicates uponiwhich' the a plurality of pairs of oppositely-disposed.

undercut flanges 2, said flanges being preferably made integral with the shaft-as shown. Each section is adapted to rest upon shaft 1 between the flanges, and is shaped to fit about said flanges, the ,several sections lying snugly against the shaft. Referring now to v Figs. 1 to 4, inclusive, section 3 is shown as comprised by a block '1 of a length equal to the distance separating a pair of flanges 2.' This block at either end thereof with a plate indicated at 3. and 5 respectively, each of which has means, as projection '6, adapted to take un- "der the undercut portions of flanges 2. In the present instance, plate'5, at one end of shown as rigidly secured thereto, the other of said plates being clamped against said block by means of a headed screw 7, which is threaded into' the block. By this means the block is securely clamped to the shaft in any desired adjusted position thereabout.

Block 4 in the present instanceis vided with a milled recess 8 ceive a. numbering head 9 or other printing device, shown hereinin dotted lines, said adapted to re head being suitably secured. cess. This head, in the resent instance, is provided with a plura it f of numbering wheels, as at 10, adapted to a plunger 11 which extends downwardly through the head. i to be engaged and actuated by means of a finger 12 fixed uponrock within said re- "Plunger 11 is adaptedseveral sections or cylinders employed to carry the printing deinvention relates to printing mech-' and more particularly to the conis provided I pro be actuated by shaft 13,,Which 4 extends longitudinally of block 4:, the outer end of which is provided with-a rocker arm 14. Rocker arm/14..- has a stud" 15 extended outwardly therefrom which carries an antifriction roller 16. This roll traverses the same as made in four periphery of a cam 17 attached to the bear- .vices through plunger 11.

In Figs. 5 to S, inclusive, shaft 1 shown as provided with another type'of cylinder, herein shown at 18. This cylinder is comprised by a plurality of sections made of the pro er height so that printing plates may be astened thereon as by means of clamps 19, whichengage .the printing plates at opposite ends thereof, thereby holding said plates against the periphery of the section.

In Fig. 5 the clamping plate at one'end ofthe drawing is shown as fastened to the sections of the cylinder b means of clamp screws 20. While the cy inder 18 may be made up of any desired number of sections. in the present instance I have shown the sections, the several sections constituting the cylinder being positioned about the shaft between a pair .of oppositely-disposed undercut flanges, and are rigidly secured to the shaft by means of clamp plates 21, each of which is provided with a projecting member fitted within the undercut portion of a flange. These plates may be secured to the sections in any desired manner. In the present instance, I have shown the platesat one end of the cylinder'as being secured thereto by means of clam screws 22 threaded into openings provide in he'sevcral sections. In this instance one of the sections indicated at 23 is provided with a longitudinally extending recess 24, the walls of which are grooved at 25, as clearly shown in Figs. 6 and 7. \Vithin this recess and at both ends thereof are provided blocks 26 and .27 respectively, said blocks being rigidly secured in said recess by means of clamp screws 28 and 2t). Blocks.-26 and 27 are also provided with oppositely-disposed tongues or kerfs 30 which are receive in the grooves 25 of recess 24.

Intermediate end blocks 26 and 27 is pr'ovided a sliding block 31 which is constructed similarly to the fixed blocks. Between this sliding block and block 27 is provided a coil spring 32 which urges the sliding block toward the other of said fixed blocks so that there may be clamped between the sliding block and fixed block 26 one or more of printing devices is indicated at 33. By t 18 means the types are securely hold upon the cylinder. Having thus described the structural features c mstitutingthis embodiment of my invention, the manner of using the same may now be understood. The several cylin- (lcl's or sections being rigidlvand securely clamped upon the undercut integral flanges of the supporting shaftmay be readily nem'oved therefrom by simply releasing the or types, one of which clamping plates by means of which the said sections or cylinders are clamped upon the flanges. The sections, as illustrated in Figs. 1 and 5, may be used together or singly, or several of either or both styles of sections may be employed upon the same shaft.

It will thus be seen that I have provided a construction well adapted to attain the several objects and aims of my invention in an exceedingly simple yet practical manner, the several sections being rigidly secured upon the shaft in such manner that they may be readily detached therefrom, as when it is desired to position other styles or forms of cylinders or sections thereon.

As many changes could be made" in the above construction and many apparently widely different embodiments of this invention could be made without ter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.- It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope'of the invention, which, as a matter of language, might be said to fall therebetween.
